What is a HSG?

A hysterosalpingogram, or HSG, is a simple medical test that uses a special dye (contrast media) and x-rays to check if your uterus and fallopian tubes are healthy and open. 

Understanding your procedure

The HSG helps doctors see the shape of your uterus and check if your fallopian tubes are open. It helps diagnose conditions such as endometrial polyps, fibroids, scarring, and is part of an assessment for fertility problems. 

This procedure will be performed with either a water-soluble contrast (Visipaque) or oil-soluble contrast (Lipiodol). 

Before your procedure

The timing of your appointment is important. It needs to be after your period has finished, but before you ovulate – between days 7 and 12 of your cycle. Call on the first day of your period to book an appointment. 

You may be given preventative antibiotics to take the day before, the day of, and the day after the HSG. 

On the day

There is no special preparation necessary on the day, however, over-the-counter pain medication taken 30 to 60 minutes before the procedure can help reduce pain, but please check with us before taking this.  You may want to wear an absorbent pad in your underwear on the day of your procedure. 

When you arrive: 

  • Please check in with reception. 
  • You will be asked to change into a gown. 
  • You will be taken to the procedure room and our radiologist will explain your procedure and ask for your consent before proceeding. 

During your procedure

  • You will be asked lie on the imaging table and made as comfortable as possible. 
  • The radiologist will use a speculum to visualize the cervix, then place a fine catheter into the cervix. The speculum is then removed once the catheter is positioned.  
  • The contrast media is gradually introduced into the uterine cavity and passes through the fallopian tubes, unless they are blocked.  
  • X-ray images are taken as the dye fills the uterus and fallopian tubes.  
  • An internal or transvaginal ultrasound may also be performed to improve assessment for uterine adhesions or endometrial polyps, and ovarian assessment is also performed. 

After your procedure

  • Any direct results will be discussed with you before you leave, and you will have the opportunity to ask questions. 
  • Most women can resume normal activities immediately following the procedure.
